Nitrogen Fertilization of Ultra-Narrow-Row Cotton: Final Report1
Recent developments in cotton (Gossypium hirsutum L.) production technology in the Delta include drill planting cotton in an ultra-narrow-row (UNR) production system. Ultra-narrow-row cotton is a low-input production system designed to maximize economic returns. The premise is that UNR cotton will be lower yielding, but the reduction in input costs will result in a larger profit margin. Researc...
متن کاملyield and fiber quality comparison of cotton planted in ultra narrow row and conventional row
management practices can affect the yield, maturity, and fiber quality of cotton. one practice used to increase yield has been to adjust the spacing between cotton rows. typically cotton is planted in row spaced 70-100 cm apart. ultra narrow row cotton production has been proposed as an economical means to increase yields and reduce production costs. a field study was conducted to assess the ef...
متن کاملManagement of Root-knot and Reniform Nematodes in Ultra-Narrow Row Cotton with 1,3-Dichloropropene.
Ultra-narrow row cotton studies were conducted during 1999 at two field sites in northern Florida. One site was naturally infested with Meloidogyne incognita Race 3 and the other with Rotylenchulus reniformis. The fumigant 1,3-dichloropropene (1,3-D) was applied broadcast at rates of 0, 16, 32, 48, 64, 80, and 96 kg ai./ha in replicated plots before planting Delta Pine 655 BRR cotton in 25-cm-w...
متن کاملComparing the Last Effective Boll Populations in Ultra-narrow-row and Conventional Cotton
Identification of the last effective boll population allows informed decisions for termination of insecticide and application of harvest aids. However, the current COTMAN cutout reference, i.e., NAWF=5 (Oosterhuis et al., 1999), may need to be changed for ultra-narrow-row (UNR) cotton. This study is part of a multi-state project which has an overall objective of determining the main-stem node n...
متن کاملCOTTON Relationships between Insufficient Potassium and Crop Maturity in Cotton
difficult to prove cause and effect for maturity differences being responsible for any variation in response Potassium deficiency in cotton (Gossypium hirsutum L.) depresses among genotypes to K. Theoretically, differences in root yield by decreasing late season growth and is reportedly more harmful to early maturing cotton genotypes. Research objectives were to detersystem size or effectivenes...
